Description
The Extended Long Travel Radius Arms by James Duff Inc. are crafted for those seeking superior off-road performance and enhanced vehicle control. Originally developed for the ’78-’79 Big Bronco, this specialized kit adapts seamlessly for Ranger-based vehicles, paving the way for a successful solid axle swap. Constructed from 2″ diameter heavy-wall DOM steel that is 5/16″ thick, these arms ensure maximum strength and safety.
With an impressive length of 10 3/4″ longer than stock ’66-’79 Bronco radius arms, the pivot point is moved backward, which significantly boosts suspension travel and articulation. This design doesn’t just excel off-road; it also optimizes handling and responsiveness during highway driving.
The kit includes heavy-duty components such as separate cast steel head units that mount directly to the C-wedges on your axle, maintaining compatibility with the original C-caps or the optional new versions. Features to note:
– Fabricated from brand new materials
– Streamlined installation with bolt-in C-channel frame mounts
– Built-in caster enhances alignment and driving dynamics
– High-quality rod ends keep the arms securely close to the frame for improved ground clearance
Designed to work best with a minimum 6″ suspension lift for Full-Size Broncos, this kit optimally integrates with various aftermarket components such as Cast C-Wedges, C-Caps, and spacers to facilitate the installation of a Dana 44 or Dana 60 axle.
Included in the kit:
– 1 Driver and 1 Passenger Side Radius Arm
– 2 Headunits
– 1 Driver and 1 Passenger Side Frame Bracket
– Hardware Kit
– Anti-seize
– Instruction Sheet
For vehicles with specific lifting requirements, C-bushings must be purchased separately to ensure proper alignment and performance. The extended arms featured in this kit are recognized for their durability and proven reliability in the off-road community.

I can’t say much for the functionality of this kit yet, as iv got more parts to order first. But the quality is great. I’m very impressed with how robust the arms are. I can’t wait to get the rest of the parts needed for my Dana 44 swap.
